[ patch removed ] Jan> It shouldn't matter. The md5 algorithm should be independent of the Jan> buffer encoding. What version are you using? XEmacs 21.2.13 with Mule[1] I will try it with recent CVS snapshot. I wonder what this is supposed to do: xemacs -vanilla -eval ' (progn (set-language-environment "Latin-2") (with-temp-file "/tmp/apel-copy" (insert-file-contents-internal "/tmp/apel-1.11-pkg.tar.gz")) (save-buffers-kill-emacs))' For me the created file (/tmp/apel-copy) is bigger than the original. Maybe insert-file-contents-internal is broken, because with insert-file-contents-literally the copies are same.
